Trade-in site NextWorth said it saw a 1,015 percent increase in iPad trade-ins yesterday after Apple's announcement of a new iPad. The company didn't say how many total iPads that jump amounts to, but it wouldn't be a surprise if a lot of burned Apple owners ran to a trade-in site following the news. The new device comes just seven months after the third-generation device's release.

A similar spurt of activity happened on another swap site, Gazelle.com, and the company said trade-ins jumped 700 percent today, a 450 percent increase from yesterday when the Apple news hit. At Gazelle, 70 percent of the trade-ins were for third-generation iPads.

Most of the trades on NextWorth yesterday -- 66 percent, according to the company -- were also for the third-gen iPads. Twenty-eight percent were for iPad 2 tablets and 6 percent were for the original iPad.

NextWorth's promotion to give customers an extra 10 percent on any iPod or iPad may have added to the increase.
